You could always move out to the country and raise your own cows, just a few, for the milk and occasionally meat. Get some chickens too, for endless eggs.
Farm a small plot of land to feed them.
Get a big freezer, resign yourself to eating meat monthly instead of weekly or daily, and you’ll be set for life with minimal impact on the environment.
Oh man this is making me jealous. I’ve not gone snow camping, but I want to.
A buddy of mine is game to do it too, just gotta find the time before winter is over.
